Russia and Ukraine struck each other with hundreds of drones on Sunday, throwing Russian air travel in disarray, days after Moscow launched its largest aerial assault in the more than 3-year-old

Ukraine said it struck a Russian air base on Saturday, while Russia continued to attack Ukraine with hundreds of drones overnight as part of a stepped-up bombing campaign that has dashed hopes for a breakthrough in efforts to end the more than 3-year-old war.

Russian air defenses on July 5 shot down four drones advancing on Moscow, prompting a temporary halt to outgoing flights at Sheremetyevo, one of the capital's main airports. Mayor Sergei Sobyanin reported emergency services at the drone downing sites but provided no immediate details on potential damage.
